I Application filed. June 4,

The object of my irn entionis to afford substantial and efi'ect ve'lockingmeans for doors and analogous closures, said locking means being practically burglar. proof in character, as hereinafter fully set forth, my improvements consisting in the spec fic com-- bination, constructionv and. arrangement; of component parts and appurtenances, de-

scribed and claimed wherebythese and other advantageous results are: attained. f I

the end" ofWhiChQprojQects intothe notch 64,

on which] a cylinderilatch key lock. K, of :the. Yale. or equivalent type is mounted, the

. ence moreparticularly to Figs. 30'jand. 31.

The said segmental rocker A, pivotall-y suJJorted on the slate b of the casing V l 7 a box B, by ineans'of ahollow boss 5, and retaining screw 7), (see Figs. QSand 29) and is formed with rack teeth a, which; engage with corresponding rack teeth 0, on the opposed edge of the lo r'or secondary segmental lOCl-I r C, whici. likewise .pivotally suppor"ed on the base plate 5, in this case on hollow studs R, (see FigsJEZS- and 29) through which the handle spindle h, extends. i

The upper primary segmental rocker A, is

ally connected with a link a which in turn 1 is pivotally connected with the lower c2:-

tremity of the upper auxiliary brace bolt'V,

' unca extendsthrough'the top flange of the i casmgbox B, and to a guide cap (Z, on'the top of the doorD, as shown in l i Lott the drawings, said guide cap d, when the door is closed, being in alignment with the socket plate j, on the upper member of the door jamb J, so that when the said auxiliary brace bolt V, is shot upward it will engage with said socketplate y', thereby reinforcing and securing the upper portion of the door against external pressure.

In like, manner the lower segmental rocker C, is formed with a lateral arm' 0, which is pivot-ally connected with a link 0 which in turn is pivotally connected with the upper extremity of the lower auxiliary brace bolt X, which. extends through the lower side flange of the casing box B, and to a guide cap Cl, on the bottom of the door D, also as shown in said Fig. 1, of the drawings, said guide cap d, when the door is closed, being in alignment with the mortise plate and socket 7, countersunk in the floor, so that when the said auxiliary brace bolt X, is shot downward it will engage with said mortise plate and socket 7, thereby reinforcing and securing the lower portion of the door against external pressure.

Thus the two auxiliary brace bolts V, and X, are adapted to positively secure the door D, in closed and bolted position independent of although controlled by the other bolt lock mechanism. In the accompanying drawings these auxiliary brace bolts V, and

X, are shown as positioned and'operating vertically, although they may be otherwise positioned and operated with substantially like results in adapting them to special requirements, as may be found most expedient.

The key lock plate M, is rigidly attached to bosses 6 6 (see Fig.29) integral with the base plate 6, of the casing by means'o'f screws, shown in Figs. 3 and 4, of the drawings'said bosses b 6 (see Figs. 3, 7 and 27,015 the drawings) supporting said key lock plate M, a sutiici'ent distance away from the base plate 0, to 'afiord accommodation for the hey-actuated shift arm 70, the hub" flanges of which are journalled respectively stood by reference more particularly to ori ied with a lateral arm a which is pivotsegmental rocker A as rocked into in tl ebase plate Z7, and in the bearing hole m in said key lock plate M, as will be underwie- 28, of the drawings, which also shows the soindletonvue 70 of the latch loci: K arotruding into the slot Z0, of said key-actuated shift arm 'k. Thus in F 1g. 30, said heyactuated shift arm 76'' is shown as in ergagement with the notch a, of the-primary se -mental rocker A, and as having itin to-position shown in 3, of inert ngs,'whercas F 1g. 31, shows said prime pcs shown in Fig. 4, thereof.

Fulcrunied onan'd between the said fixed lock plateM, and the cover-plate B of the box casing B, is the hand shift-leveof the key-actuated shift arln'lcfl the end of the rockshaft s, on which salt. hand rocked p S, the shafts of which JS'llI axial ali 'nment with.

shift lever S,'is rigidly'mounted being journailed in the aforesaid bearing hole m, in

the key lock plate hi, and; the outer end of said rock shaft 8, being journalled in the" bearing hole 6 formed for the'purpose in the cover plate B, as'clearly shown in 28, of the drawings, the protuberant cu end ofssaid rock shaft 's,'having rigidly a tached thereto the finger switch 8, by means of which said shaft 8, and its switch lever S,

.may be rocked alternately in opposite .rections to shift the spring pawl P, from one mortise notch m, in the key lock plate M, to the other mortise notch m therein and vice versa,sa-id spring pawl'P, being con. nected with the hand shift lever S, by means of a coupling pin p',"on the pawl P, which in rotrudes into the lon 'itudinal slot 8', formed for the purpose in the shift lever S, aswill be understood. by reference more particularly to Figs. 3, 4:, '5 and 20, of the drawings.

The spring pawl P, is slidably mounted upon the face of the segmental rocker A,

its shank g), resting between fixed guide shoulders a on the upper portion of sa d primary segmental rocker A, and its stem rod 79 engaging with an eye luga, on the lower portion of said, primary segmental rocker A, adjacent to the gear teeth a, there on, and a coiled spring p beinginterposed onsaidstem rod pabetween the-eyeing a ,"and the shank p, of the pawl P, said spring tending constantly'to maintainflengagementof the. nose of said pawl with the key lock plate M. o

The spring pawlP, is formed, below the, couplingrpin p, with a bearing shoulder 20", for contactual engagement with the end of the hand shift lever S, when the latter is moved in either direction to shift the pawl P, and the primary segmental rocker A, on Whichit is mounted, said hand shift .lever S,

neon-use being of sufficient length to depressin transit the paw i, against the resistance ofthe spring 71 so that the nose of the pawl is released from the mortise notches m, 772 in the key lock plate M, to admit of the shifting of said primary rocker A, from one po-' sition to the other.

A lateral extension p of the spring pawl- P, has rigidly secured to it a push rod or member 37, the upper end of which, when the parts of the locking mechanism are in the relative positions shown in'Fi'g. l, of

the drawings with the j amb mortise bolt I, and auxiliary brace bolts E, Gr, shot, is in of the drawings, Hence, under these condi tions, any attempt to force back either of the aforesaid bolts, will result 1n suffic ent movement and pressure exerted upon and through the medium of the meshed segmental rockers A, C, to actuate. said alarm device IV, and thus frustrate surreptitious entrance; i I

The jamb mortise bolt I, is connected with the lower extension 0 of the secondary seg mental rocker C, by means of'a'stud 2', protruding into an elongate slot 0 in said extension 0 as indicated by dotted lines in Figs. 3 and l, and in sectional elevation in Fig. :28, of the drawings. 7

L, is the spring snaplatch formed with the usual bevelled outer end Z, and held normally thrust outward by means of the leaf spring n, the lower end of which bears against the transverse shoulder Z, formed for the purpose on the forward portion of said latch L, behind the snap bevel Z, the

rear portion of said latch L, being'formed' with the longitudinal slot Z which straddles the axial sleeve 1", integral with the duplex cam 33., the arms of which engage contactually with the transverse abutment Z on the inner extremity of said spring snap latch L, as shown more particularly in Figs. 3 and l, of the drawings, and the said axial cam-sleeve r, beingmounted on the handle spindle h, and conforming internally to the angular cross section thereof, so that the turning of either of the handles H, II, in -itl1er direction will retract said snap latch L, against the resistance of its spring a, the upper portion of which latter is. held fixedly upon the base plate Z), by binding contact with, and between the stud Z2 and one of the bosses Z1 on said base plate I). i What I claim as my invention and desire to secure by Letters Patent, is
